Access the particle system trails module.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var trails = ps.trails; trails.enabled = true; trails.ratio = 0.5f; } }
| attachRibbonsToTransform | Adds an extra position to each ribbon, connecting it to the location of the Transform Component. |
| colorOverLifetime | The gradient controlling the trail colors during the lifetime of the attached particle. |
| colorOverTrail | The gradient controlling the trail colors over the length of the trail. |
| dieWithParticles | If enabled, Trails will disappear immediately when their owning particle dies. Otherwise, the trail will persist until all its points have naturally expired, based on its lifetime. |
| enabled | Enable/disable the Trail module. |
| generateLightingData | Configures the trails to generate Normals and Tangents. With this data, Scene lighting can affect the trails via Normal Maps and the Unity Standard Shader, or your own custom-built Shaders. |
| inheritParticleColor | Toggle whether the trail will inherit the particle color as its starting color. |
| lifetime | The curve describing the trail lifetime, throughout the lifetime of the particle. |
| lifetimeMultiplier | Change the lifetime multiplier. |
| minVertexDistance | Set the minimum distance each trail can travel before a new vertex is added to it. |
| mode | Choose how particle trails are generated. |
| ratio | Choose what proportion of particles will receive a trail. |
| ribbonCount | Select how many lines to create through the Particle System. |
| shadowBias | Apply a shadow bias to prevent self-shadowing artifacts. The specified value is the proportion of the trail width at each segment. |
| sizeAffectsLifetime | Set whether the particle size will act as a multiplier on top of the trail lifetime. |
| sizeAffectsWidth | Set whether the particle size will act as a multiplier on top of the trail width. |
| splitSubEmitterRibbons | When used on a sub emitter, ribbons will connect particles from each parent particle independently. |
| textureMode | Choose whether the U coordinate of the trail texture is tiled or stretched. |
| widthOverTrail | The curve describing the width, of each trail point. |
| widthOverTrailMultiplier | Change the width multiplier. |
| worldSpace | Drop new trail points in world space, regardless of Particle System Simulation Space. |
